针对常用的电机矢量控制系统中不考虑铁损的问题，为优化电机运行效率，提出一种基于滑模变结构的感应电机效率优化控制技术。在感应电机两相静止坐标系中建立了并联电阻型电机损耗模型；设计了基于二阶滑模的控制器，并利用超螺旋控制算法解决了相关度为1的滑模控制中抖动问题；利用李亚普诺夫稳定定理，证明了该控制系统的稳定性，同时推导出相应控制器的增益参数。 Matlab Simulink仿真结果表明：基于滑模的效率优化控制方法不仅能够降低电机损耗，提高电机运行效率，而且具有很好的动态调速性能，抗干扰性好，鲁棒性强。

For the optimization of motor efficiency, a kind of control efficiency optimization of induction motor based on slid-ing mode variable structure is presented to solve the problem without considering the iron loss of motor vector con-trol system. The parallel resistance motor loss model in the two-phase stationary coordinate is set up. The con-troller is designed based on the two order sliding mode, and solves the problem of chattering of sliding mode con-trol for the correlation degree 1 by the super twisting algorithm. The stability of the control system is proved by Lyapunov stability theorem, and the gain parameter of controller is deduced. Matlab Simulink simulation shows that the efficiency optimization control method based on the sliding mode can reduce the motor loss , improve the operating efficiency of the motor, has good dynamic speed performance and good anti-interference performance and strong robustness.
